I treated myself to a bike equipped with this and I will want to make a couple of changes. Basically I want to add some base bar shifters at present it only has shifters on the aero bars, great for time trials but I will be riding some spoco and possibly Lanza or Wales.

The ‘control junction box thingy’ under the stem doesn’t have any spare ports so I will need a 5 outlet box then how do I connect it all up?

As I am a technological numpty is it a job for an expert?

Any help appreciated

It is really simple, but you will need the special unit to connect to your PC to configure the setup. I hired one a couple of times from my LBS, but ended up buying one on ebay eventually.

The advantage of having the connection box is that you can get all of the updates to your DI2, and play around with different configurations. Apparently if you have an internal battery, the latest update has some nice options such as automatically dropping the cassette by 1 or 2 gears when you change from small to large ring on the chainset

Thanks Matt how long until you set a cadence range and the bike does all the shifting for you ....like erg mode on a smart trainer.

Cheers for help

Bikes with automatic gearbox. I once thought it was a joke but instead of cadence you don't need much more than a powermeter and it'd be possible?
